Review of the Tamron 18-400mm F/3.5-6.3 DI-II VC HLD Zoom Lens


Tamron has been specializing in super-zoom lenses for the last few years. You may be familiar with their 16-300mm, 18-270mm or 150-600mm lenses. Their newest super-zoom is an even more astonishing focal length, the Tamron 18-400mm. I recently had a chance to review this lens for a few weeks so I thought I’d give you an idea of who this lens is for, the good, the not-so-good, and my overall recommendation.

About this review

I know you already know this (because you read ALL my pieces for dPS, right? Right?!) but my lens reviews are pretty real world. I don’t sit in a lab or use techy gizmos to measure sharpness. I actually hold a lens in my hands and shoot with it. This lens was tucked in my favorite bag for most of August.

That said, my intention was to see how a lens holds up for an actual shoot. I used this lens to photograph Lipizzan horses at a dressage performance as well as at the racetrack. Then I used it on a mission to photograph old barns and finally to make some macro flower images.

The goal was to make images at most focal lengths with a variety of apertures, but a few might have been skipped because I was really out there shooting. I shoot at the focal length, shutter speed, ISO and aperture that each situation calls for. So let’s just say I apologize in advance if I’ve skipped something important to you. Give me a shout in the comments if that’s the case. I’ll dig through my notes and image archives to see if I can answer your question.

Lens specs

Let’s start off with a quick overview of the lens specs. This lens is for Nikon and Canon APS-C (crop sensor) cameras only. I tested the lens on a Canon 7D Mark II.

The Tamron 18-400mm super-zoom is a variable aperture lens. Meaning that at 18mm, the maximum aperture (largest opening) is f/3.5. But when you zoom into 400mm, the maximum aperture is f/6.3. The minimum aperture (smallest opening) is f/22 at all focal lengths.

The lens has an HLD Autofocus Motor that is quick and quiet for a consumer lens at this price. It also has Tamron’s standard VC Image Stabilization. This feature enables you to get sharper shots while hand-holding at longer focal lengths. The lens also has what Tamron calls Moisture-Resistant Construction. I’m relieved to tell you I didn’t get to test this feature.

The minimum focusing distance – important especially if you want to try your hand at making macro images – is 17.72″ (45 cm). Macro is usually a 1:1 ratio and this lens only produces 1:2.9, but I was pleasantly surprised with my macro results.

If you use screw on filters, like a circular polarizer, the front thread is 72mm. The lens is 1.56 pounds (710 g) and approximately 3.11” in diameter by 4.88″ in length (79 x 123.9 mm). It’s an incredibly compact lens for this focal length range.

The price, at the time of publication of this article, is $649.00 USD.

Who is this lens for?

I would describe the ideal user of this lens as an amateur or enthusiast. If you’re an amateur photographer who travels but doesn’t want to carry more than one or two lenses, this is the perfect choice for you.

With an 18-400mm focal length, you might not need to ever change the lens, except in a dark indoor situation, when you need either flash or perhaps the fast f/1.8 maximum aperture of a nifty fifty.

This lens would also be great for a busy parent who needs more than a smart phone to capture pictures of soccer matches and dance recitals but who doesn’t have a ton of extra room in her carryall bag. The compact size and weight of the Tamron 18-400mm make it an easy addition to any parent’s standard kit.

What’s good about this lens

The size of this lens just can’t be beat. At only a pound and a half and less than 5 inches long, it’s a lot of focal length in a very small package. I was really taken with how small it was since I normally shoot with such large neck-and-shoulder-busting glass.

Hand-holding this lens for an afternoon at the race track wasn’t even remotely painful. With the insane focal length capabilities, I didn’t even bother to carry a second lens with me (or even my camera bag!) and that made for a really care-free afternoon.

Great for landscape images

It’s also a pleasure to catch a pretty landscape out of the corner of your eye and to simply zoom out to 18mm to capture it. Typically if you’re shooting with a long lens, you have to take the time to switch over to your wide-angle lens, take the shot and then switch back to your longer focal length lens again. Well, actually, if you’re me, you see that landscape and think ooh, pretty and then walk away without taking the shot.

I’m lazy that way so this was the first time I’ve actually made images of the racetrack itself. The lens performed really well in the 18-50mm focal range. It was both sharp and relatively distortion free. Lightroom’s Lens Correction easily managed the slight distortion there was too.

Things to be careful of

Remember I said we’d talk about the not-so-good too? It is a touch tricky to twist the lens in order to zoom in past 200mm to get to the 400mm focal length. First, your hand gets a bit “stuck” since anatomically, your wrist only twists so far before you have to reposition in order to continue the twisting motion.

Second, the lens has what I call a “hiccup” where you need to exert more pressure to push it past this point. I missed a few shots because the twisting motion wasn’t smooth enough and I jerked the lens a bit as I zoomed in from 200mm to 400mm.

Softness around the edges

There is a definite softness (or loss of sharpness) at the longer end of the lens, especially when your aperture is wide open, e.g., 400mm at f/6.3. If you crop in too much during post-processing or print too large, you’ll start to see the loss of fine details in your image since they weren’t tack sharp to start. You won’t see this loss of detail in a small 5×7″ print, or if you post to social media – so for many people, this actually won’t be a big issue.

Tamron 18-400mm lens Review - Riders up

Riders up at the paddock, Arlington Park IL. Canon 7D Mark II, Tamron 18-400mm lens @ 18mm, f/5, 1/500th, ISO 640, handheld.

Use the center focus point

The lens tends to be softest in the corners so sharpness improves if you use your camera’s center focus point. It also improves if you close down your aperture to f/8, f/9, or smaller. Because the lens is not tack sharp all the way through the focal length spectrum, I’m not recommending this lens for super serious wildlife shooters or anyone who likes to print really large. For you guys, I’m going to suggest sticking with a more standard zoom lens like a 100-400mm or 200-400mm. (I apologize in advance for the wear and tear this recommendation will cause your shoulders.)

If you predominantly shoot wide-angle images, like landscapes, and only occasionally shoot long, this lens will be a good fit for you when you don’t want to carry a ton of gear.

Final thoughts

Ultimately there were a number of things I really liked about this lens. The small size and super-zoom focal length make it a very practical tool to have in your bag. At $649.00 USD, it’s also a great value.

However, the softness at the long end of that focal length can become a real issue if you’re not careful. Because of that, I’m cautiously going to rate this lens 3.5 stars out of 5.

I’d love to hear your opinions too. Have you tried super-zooms lenses? Do they work for your type of photography? Which is your favorite one and how does it compare to the Tamron 100-400mm lens? Please share your thoughts with the dPS community in the comments below.

    Amazing that they can pack decent quality in such a package.

  • Lara Joy Brynildssen

    It is amazing. This lens is quite small.

  • Dan Merkel

    OUCH! I thought 3.5 out of 5 was pretty low compared with my experience with the 18-400. Mine’s on a Nikon 7200 and since I got it, it has been my “standard” lens. I’ve used it since mid August and have used it for everything from close-ups to portraits, from landscapes/sunsets to birding, with & without flash and have been very satisfied with my results.
    I’ve shot groups, kids, birds, flowers, construction sites, trains (my favorite) and a host of other subjects. The only real negative that I’ve encountered is that at extreme focal length and wide open one tends to get a vignette effect. But given the zoom range and the price, my personal feeling is that this is an EXCELLENT VALUE and would be more than satisfactory for all but the most demanding shooter.

  • Lara Joy Brynildssen

    I’m glad you’ve had such a good experience with it. I’m sure that will make Tamron very happy to hear:)

  • Sabya Ghosh

    Thanks Dan for your inputs. I love birding and hence would be interested to look at some of your birding images with D7200 and Tamy 18-400mm, which I understand you use. I am planning to invest on this and am a bit hung over this and Tamron’s 150-600 G1. Can you help?

  • Max

    Hi Dan. I own a nikkor 18-140mm on a nikon D5500. I’m considering to buy this tamron 18-400 but I’m concerned about its sharpness when compared to my nikkor 18-140. Any experience? Thanks

  • John Sands

    I’m just getting started with this lens on my Canon 7D. I have trouble hand holding at 400. As I look at the long shots from this article I wonder why my results are not as good. Either I’m not steady enough or the lens is not very sharp. Thoughts?

  • Lara Joy Brynildssen

    Hmmm. I was using a 7DII. Could be partly it. Look at your shutter speed. Make sure it’s over 1/500th when you’re at the long end of the lens. Focus using the center focal point, I found that was the sharpest part of the lens. And keep trying. It took me a while to make this lens do what I wanted it to….

  • dutilleul

    I’ve had a light tamron 18-200mm attached to my superlight 100D. They went with me everywhere all the time.
    Recently I dropped them on a cement floor and it was to much for the tamron… I really loved that lens.
    Since than I’ve been using one of those fabulous prime compact lens and I feel like a grotesque ballerina going back and forth whenever I make a picture.
    Just bought the 18-400mm a few minutes ago on ebay and already trying to track it.
    If it is up to the 18-200, I will be a very happy guy.

  • Boby


  • Shirley Colomb

    How do you think this lens will do with shooting vintage aircraft’? All my readings say use a 400.

  • Lara Joy Brynildssen

    That’s a subject I’ve never photographed so I can’t make a good assessment. Sorry!

  • Lara Joy Brynildssen

    Best of luck with the new lens.

  • Jaime Gregory

    How about with sports photography? I’m still new/learning, but my son plays lacrosse and I’d like closer shots than I get with my 55-300. Thoughts?

  • Lara Joy Brynildssen

    It will work for that. Make sure to use the
    center focus point for crisper shots.

  • Jaime Gregory

    Great! TYSM!

  • Pierre Bélanger

    Hi, I was at a camera dealer and I was asking the camera expert about this lens (Tamron 18-400mm)
    and at my surprise, he mentioned about this lens that it’s only problem was the Chromatic Aberration that was apparent and can be tweeked & fixed on utilising a software such as Lightroom to fix it up !!

    I’d like to hear your thoughts about this issue… if there is one really !!!
    Thanks for your comments…
    Pierre Bélanger

  • Lara Joy Brynildssen

    Most lenses have some sort of chromatic aberration. It’s usually easily fixed in Lightroom. Of more concern with this lens is whether it is sharp enough for the type of images that you make.

  • Diego Otero

    Will this lens work with a Nikon D90?

  • Nandkumar

    Hi. I am a amateur photographer and using Canon EOS 1100D. I am using 55-250 Canon lens for wildlife photography. How about 18-400mm F/3.5-6.3 Di ll VC HLD?Model B028? for wildlife photography. Is it compatible with Canon EOS 1100D

  • richard gold

    Ms. Brynildssen,
    The last image in your post was of the “Running Lipizzan Foal…” and displayed marked blurring of the trees on both sides of the image. They might have been outside of the DoF of the lens at that point but they were a mess. Did you think they were a disproportionate mess compared with other long lenses you have used? Thanks.

  • Lara Joy Brynildssen

    I think that was partly DoF tho the lens is much sharper at the center than at the edges. It might have been windy too. It also might look like they were “a mess” because moderately priced lenses don’t often produce that same creamy blur that expensive lenses do.

  • richard gold

    Ms. Bryndilssen,
    Thank you so much for your reply. I agree that there could have been some wind and that many factors may have contributed. I was very interested in this lens but at
    close to $750 with tax I will pass. It certainly has all the quirks of all these very comprehensive mm offerings. I will probably stick with my Canon 18-200 which I always thought was quite good and that gives me 320mm with my 7DII. Thanks again for a helpful review. Richard

  • Debbie Harry

    Hi Sabya Ghosh,
    I have been using the Tamron 150-600 for 2 years now, using it for all forms of sport, bird life and people from a distance. Sharp all the way and reasonably fast. I use it on a Canon 650D, combined weight of 3.6kg. Absolutely love it. I’m now considering the 18-400 to replace a kit lens. Below is a photo I took with the 600mm

  • Sabya Ghosh

    Thanks Debbie, that was great picture. Am more interested to know about a combination of D7200 with a Tamron 18-400mm. How would that be for birding?

  • Lara Joy Brynildssen

    Nice image. Keep in mind that the 150-600 is a different sort of lens altogether than the 18-400.

  • Lara Joy Brynildssen

    Sabya, your best best is to rent the 18-400, use if for a birding trip and then evaluate your results before buying the lens. Good luck.

  • Naveen Kumar

    hello everybody ,
    I am using canon D 5200 . tell me that Tamron 18 – 400 mm is compatible to this or not .

  • Ian Lee

    Yes, it works fine with a d90…attached shot at 350mm ISO1000 f6.3, 1/1600

  • Gary Naka

    As long as it is a DAY game.
    The lens is too slow for night games under lights.

  • Gary Naka

    A 400mm lens on a 1.6x crop body = 640mm FF equiv. = 12.8x telescope.
    YES you are likely NOT steady enough.
    Anything over 400mm FF equiv, you need to use good hand holding techniques, regardless of optical stabilization in the lens or not.
    At 400mm, you should be shooting at a minimum of 1/500 sec, preferably faster, with IS on.

  • If you buy the one for the Nikon it is.

  • Matthew Burn

    Great article; how does this lens stack up against the Tamron 16-300?
    I have had a lot of use out of mine, but am looking for more range for wildlife shoots

  • GAR9

    From what I understand, a 1.6 crop is sxactly what it says, a crop. The 1.6 doesn’t actually increase the magnification, turning a 400 into a 640. What happens is that you still have have a 400mm but with the smaller field of view that a 640mm lens would have. For the image that is within frame, it’s just the same as a 400mm full frame would be. It’s just the full frame will take in more area than the 1.6 will.

  • Gary Naka

    I don’t know where my post disappeared to.

    A 400 is a 400, no mater the camera it is put onto. The focal length of the lens does not change.
    Admittedly, the confusing term is “FF equivalent.” That is trying to normalize everything to what a FF camera would see.
    – A 400mm lens on a 1.6x crop camera (22.2×14.8 sensor) has a 3 degree 49 min diagonal angle of view
    – A 640mm lens on a FF camera has a 3 degree 52 min diagonal angle of view
    Both are essentially the same, which is explaining the “FF equivalent”

    If you want to do the angle of view here is the site.
    You have to plug in the sensor size and focal length of the lens.

    So by changing the FoV, the magnification of the lens will change based on the film/sensor size.

    If we use the “normal lens” of a sensor format as 1x or zero magnification.

    For a FF camera with a 50mm normal lens, the 400 = 400/50 = 8x

    For an APSC crop camera with a 35mm normal lens, the 400 = 400/35 = 11.4x
    However using a different formula 400mm x 1.6 crop = 640 FF equiv mm. Then 640/50mm FF normal = 12.8x
    Note: The magnification difference is due to, 50mm FF normal lens / 1.6x crop = 31.25mm vs. 35mm which is the standard production normal lens for an APS-C camera.
    If you substitute; 400/31.25 = 12.8x

    So the crop is also a magnification factor of the lens, relative to a FF camera.

  • Major Crosby

    I really enjoyed your article as I had a few concerns about this lens which you covered. I’ve had this lens for about 8 months, but haven’t really taken it through its paces with my Canon SL1. I agree with the ease of carrying a light lens and light camera body combination. Again, thanks for such an informative article. I am now ready to put the lens through its paces.

  • vp


    I have the Tamron 18-300mm attached to a Canon 60D and have had a wonderful time with this lens. My other lens is a Canon EFS 17-55mm 1:2.8 which is outstanding for close range photography.

    Unfortunately my Tamron is not working very well anymore, as a screw went loose inside the lens and after hopping around it managed to get lodged somewhere in the mechanism preventing the lens from retracting all the way. The lens still works, but it will not lock closed for transport but worse its been derated to a 70-300mm lens which is not very convenient.

    For a lens that has had a fairly comfortable life (no scratches on the body at all) the loose screw is a serious indication of poor workmanship.

    Too bad.


  • 140960johan

    When I use my Tamron 18-400 with my old Nikon D80 camera, it overexpose. With my D610 camera it is good . (i tried it on auto or Aperture settings)
    Is the Tamron not compatible with the old D80?
